The selection function of the Gaia DR3 open cluster census
Emily L. Hunt, Tristan Cantat-Gaudin, Friedrich Anders +4
Open clusters are among the most useful and widespread tracers of Galactic structure. The completeness of the Galactic open cluster census, however, remains poorly understood. For…
The completeness of the open cluster census towards the Galactic anticentre
Emily L. Hunt, Tristan Cantat-Gaudin, Friedrich Anders +9
Open clusters have long been used as tracers of Galactic structure. However, without a selection function to describe the completeness of the cluster census, it is difficult to qua…
The realm of Aurora. Density distribution of metal-poor giants in the heart of the Galaxy
Evgeny P. Kurbatov, Vasily Belokurov, Sergey Koposov +11
The innermost portions of the Milky Way's stellar halo have avoided scrutiny until recently. The lack of wide-area survey data, made it difficult to reconstruct an uninterrupted vi…
GaiaUnlimited: The old stellar disc of the Milky Way as traced by the Red Clump
Shourya Khanna, Jie Yu, Ronald Drimmel +9
We present an exploration of the Milky Way's structural parameters using an all-sky sample of RC giants to map the stellar density from the Galactic disc beyond 3 kpc. These evolve…
OCCASO V. Chemical-abundance trends with Galactocentric distance and age
J. Carbajo-Hijarrubia, L. Casamiquela, R. Carrera +12
Context. Open clusters provide valuable information on stellar nucleosynthesis and the chemical evolution of the Galactic disc, as their age and distances can be measured more prec…
How Gaia sheds light on the Milky Way star cluster population
T. Cantat-Gaudin, L. Casamiquela
Star clusters are among the first celestial objects catalogued by early astronomers. As simple and coeval populations, their study has been instrumental in charting the properties…
Gaia DR3 detectability of unresolved binary systems
Alfred Castro-Ginard, Zephyr Penoyre, Andrew R. Casey +10
Gaia can not individually resolve very close binary systems, however, the collected data can still be used to identify them. A powerful indicator of stellar multiplicity is the sou…
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Uniting Gaia and APOGEE to unveil the cosmic chemistry of the Milky Way disc
Tristan Cantat-Gaudin, Morgan Fouesneau, Hans-Walter Rix +6
The spatial distribution of Galactic stars with different chemical abundances encodes information on the processes that drove the formation and evolution of the Milky Way. Survey s…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Parameter Estimation for Open Clusters using an Artificial Neural Network with a QuadTree-based Feature Extractor
L. Cavallo, L. Spina, G. Carraro +7
With the unprecedented increase of known star clusters, quick and modern tools are needed for their analysis. In this work, we develop an artificial neural network trained on synth…
Investigating Gaia EDR3 parallax systematics using asteroseismology of Cool Giant Stars observed by Kepler, K2, and TESS I. Asteroseismic distances to 12,500 red-giant stars
Saniya Khan, Andrea Miglio, Emma Willett +10
Gaia EDR3 has provided unprecedented data that generate a lot of interest in the astrophysical community, despite the fact that systematics affect the reported parallaxes at the le…
Estimating the selection function of Gaia DR3 sub-samples
A. Castro-Ginard, A. G. A. Brown, Z. Kostrzewa-Rutkowska +9
Understanding which sources are present in an astronomical catalogue and which are not is crucial for the accurate interpretation of astronomical data. In particular, for the multi…
The multiplicity fraction in 202 open clusters from Gaia
J. Donada, F. Anders, C. Jordi +7
In this study, we estimate the fraction of binaries with high mass ratios for 202 open clusters in the extended solar neighbourhood (closer than 1.5 kpc from the Sun). This is one…
The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
Shoko Jin, Scott C. Trager, Gavin B. Dalton +212
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree…
An empirical model of the Gaia DR3 selection function
Tristan Cantat-Gaudin, Morgan Fouesneau, Hans-Walter Rix +11
Interpreting and modelling astronomical catalogues requires an understanding of the catalogues' completeness or selection function: objects of what properties had a chance to end u…
The Structure and 3D Kinematics of Vela OB2
Joseph J. Armstrong, Nicholas J. Wright, R. D. Jeffries +2
The kinematics of stars in OB associations can provide insights into their formation, dynamical evolution, and eventual fate. The low-mass stellar content of OB associations are su…
Cluster Cepheids with High Precision Gaia Parallaxes, Low Zeropoint Uncertainties, and Hubble Space Telescope Photometry
Adam G. Riess, Louise Breuval, Wenlong Yuan +6
We present HST photometry of 17 Cepheids in open clusters and their mean parallaxes from Gaia EDR3. These parallaxes are more precise than those from individual Cepheids (G<8 mag)…
A new resonance-like feature in the outer disc of the Milky Way
Ronald Drimmel, Shourya Khanna, Elena D'Onghia +18
Modern astrometric and spectroscopic surveys have revealed a wealth of structure in the phase space of stars in the Milky Way, with evidence of resonance features and non-equilibri…
